How to get in the language plugin all PsiFiles or certain file by name from the project?
Please see http://confluence.jetbrains.net/display/IDEADEV/IntelliJIDEAArchitectural+Overview for more information. Note that in most cases you don't ever need to get all PsiFiles (that would be unusably slow in a real-life-sized project in any language).

As I wrote above, this code will be unusably slow in any real-life project. A better solution is to find an approach to solving your issue that does not require getting all PSI files in a project.
Hello Oleg,
Please see http://confluence.jetbrains.net/display/IDEADEV/IntelliJIDEAArchitectural+Overview
for more information. Note that in most cases you don't ever need to get
all PsiFiles (that would be unusably slow in a real-life-sized project in
any language).

The only solution I found is the next:
public static List<PsiFile> allProjectFiles(@NotNull Project project) {
final PsiManager psiManager = PsiManager.getInstance(project);
final PsiDirectory prjDirectory = psiManager.findDirectory(project.getBaseDir());
return prjDirectory != null ? getFilesRecursively(prjDirectory) : Collections.emptyList();
}
private static List<PsiFile> getFilesRecursively(@NotNull PsiDirectory psiDirectory) {
List<PsiFile> psiFileList = new ArrayList<>(Arrays.asList(psiDirectory.getFiles()));
for (PsiDirectory subDir : psiDirectory.getSubdirectories()) {
psiFileList.addAll(getFilesRecursively(subDir));
}
return psiFileList;
}
Unfortunately, deprecated Project#getBaseDir() method is used here...
Will appreciate for any better solution. (Dmitry Jemerov ?)
